PETG Filament is short for polyethylen Terephthalateco-1, 4-cylclohexylenedimethylene terephthalate, and is a transparent type of coplyester. It claims to be a material strong like ABS and easy to print like PLA.Chemically different from a number of other printing filaments, it can be printed at a low temperature without pre-drying, and should hardly stick to your print bed.Despite its high level of toughness and impact strength, it remains very flexible and recyclable, despite its transparency. It's also odorless during printing and features a low shrink rate, while not suffering from warping as ABS often does. Aside from the natural transparent version, it also comes in Magenta, Yellow and Blue.Its full printing specifications are:Print temperature：200~240°cPlate temperature：75~85CPrinting speed：30~60mm/sMoving speed：30~60mm/s
